Graphene is the way. Virtually super conducting (no loss of electricity traveling through it. It is hundreds of times stronger than steel. Several times harder than diamonds. Lighter than air... Corrosion proof. Flexes and stretches. And can be made out of common items, like from the graphite in your pencils when you were in school. Or coal, or old tires, or sugar, or wood or....
Look up graphene batteries, graphene super capacitors, graphene tires, graphene solar cells, graphene fuel cells ( the kind that makes electricity from hydrogen), to name a few. Its abundant everywhere.
Homes may very well no longer need the electric companies, and be able to make and store the power they need thanks to graphene. When you move graphene over nano diamonds there is no friction, so no wear nor loss of power from friction.
Graphene is todays buzz word, just as plastic and silicone use to be. It may detect and cure many diseases, and make wars impossible. Graphene is highly bullet and fire proof and is naturally transparent. It transfers heat 12 times or more better than copper.
Now you can dream of the graphene rods or cranks, or the whole engine, drive-trains,, and bodies and windshields, but the fact is who will want them with any combustion engine. People use to love the horse and buggy and hayrides and there are still a few around.
Lithium will be replaced by graphene. Steel, aluminum, and the rest also. Graphene can both make and store the power. Graphene can make power from light, and rain, and wind, and hydrogen, and maybe able to filter the hydrogen out of the air.
Here is a youtube channel I have been watching on this

Or you can also just google graphene.
